This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.
The WebGLRenderingContext.commit() method pushes frames back to the original HTMLCanvasElement, if the context is not directly fixed to a specific canvas.
void WebGLRenderingContext.commit()
var htmlCanvas = document.createElement('canvas');
var offscreen = htmlCanvas.transferControlToOffscreen();
var gl = offscreen.getContext('webgl');
// ... some drawing using the gl context ...
// Push frames back to the original HTMLCanvasElement
gl.commit();
Currently drafted as a proposal in the OffscreenCanvas specification.
